This appendix is part of the thesis “Status and trend of brook lamprey
(Lampetra planeri) populations in Flanders”. It provides a
dynamic map and table illustrating the total number of sample events in
each watercourse and the success rate at which brook lamprey was caught.
All watercourse of the VHA (Flemish Hydrographic Atlas) can be viewed
when zooming in. The VHA watercourses disappear when changing the base
map due to a bug in coding. This can be resolved by reloading the page.
Figure C1 shows a map with an overview of the sample events and success
rate over all watercourses. The number of sample events within each
watercourse is visualized as the linewidth. The success rate of catching
brooklampreys is shown in a color scale, green corresponds to a success
rate of 100%, yellow is 50% and red is 0%. Watercourses that did not
have any available data of sample events are show in blue. The
watercourses are underlayed with the Population areas. This layer can be
ticked off if only the overview of the sample events and success rate is
needed.
